Code Description

ICD-10 A77.2 is a billable code used to indicate a diagnosis of toxoplasmosis, unspecified.

Key Diagnostic Point:

Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii, which can be transmitted through various routes, including ingestion of undercooked meat, contaminated water, or exposure to cat feces. The infection is often asymptomatic in healthy individuals but can lead to severe complications in immunocompromised patients, such as those with HIV/AIDS or undergoing chemotherapy. In pregnant women, Toxoplasma infection can result in congenital toxoplasmosis, leading to serious outcomes for the fetus. The unspecified designation indicates that the clinical presentation does not fit into more specific categories of toxoplasmosis, such as ocular or congenital forms. Diagnosis typically involves serological testing for Toxoplasma antibodies, and treatment may include antiparasitic medications, particularly in severe cases. Understanding the epidemiology of Toxoplasma is crucial, as it is a vector-borne disease that can be influenced by travel-related factors, especially in regions where the parasite is endemic.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of clinical presentations and symptoms
  • Differentiation from other vector-borne diseases
  • Need for serological testing and interpretation
  • Potential for co-infection with other pathogens

Audit Risk Factors

  • Inadequate documentation of exposure history
  • Failure to specify the type of toxoplasmosis
  • Misinterpretation of serological test results
  • Inconsistent coding with clinical findings
